Participants

Reaction Steps

37 mmol of ammonium formate and 300 mg of 10% Pd/C are added to 3.71 mmol of 5,5-dioxo-7-nitro-2,3,3a,4,-tetrahydro-1H-pyrrolo[2,1-c][1,2,4]-benzothiadiazine suspended in 100 ml of methanol. After 90 minutes' stirring at reflux, the catalyst is filtered off while hot and rinsed with methanol. The filtrate is evaporated and the residue is taken up in water. The expected product is obtained by filtering off the precipitate.
